Why we read it this way (6)
SOC classification is Medium confidence: the role is framed as infrastructure engineering and optimization of a Mainframe platform (operating systems, hardware, capacity/performance), which aligns with 15-1244 (Systems Administrators). However, the JD also calls for designing complex system upgrades, developing specifications, and driving solutions — work that edges toward 15-1252 (Software Developers). 15-1244 was chosen because the primary day-to-day work is operating, tuning, and maintaining the mainframe environment rather than shipping new software.
IBM Mainframe Hardware is listed in the required qualifications specifically referencing z15, z16, and z17 models; these are treated as a single hardware-platform requirement.
OMVS, USS, and ishell are all components of the z/OS UNIX System Services environment; they are grouped under OMVS as the canonical name. ZFS (z/OS file system) is listed separately as it is a distinct subsystem.
Chargeback processing was omitted as a skill — it names a business process rather than a specific technology or tool.
RACF carries a '2+ years' qualifier but appears under Desired Qualifications, so it is marked preferred with the years demanded of 2.
The role explicitly states it does not provide visa sponsorship and requires 24/7 on-call availability including nights, weekends, and holidays.
